[FIXED] Automatically find the path of the python executable

Issue

I'm doing a project that uses python as background script and C# as guy. My problem is that I can't figure out how to cause my GUI to automatically search for the pythonw.exe file in order to run my python scripts.

Currently I'm using this path:

ProcessStartInfo pythonInfo = new ProcessStartInfo(@"C:\\Users\\Omri\\AppData\\Local\\Programs\\Python\\Python35-32\\pythonw.exe");

but I want it to auto detect the path of pythonw.exe (I need to submit the project and it won't run on others computers unless they change the code itself)

Any suggestions may be helpful.

Solution

You can find python installation path by lookup following keys on windows machine.

HKLM\SOFTWARE\Python\PythonCore\versionnumber\InstallPath

HKCU\SOFTWARE\Python\PythonCore\versionnumber\InstallPath

for win64 bit machine

HKLM\SOFTWARE\Wow6432Node\Python\PythonCore\versionnumber\InstallPath
